Off-road ABS
An AB
Ssystem specifically suited to off -road
ter rain is activated automatically once th eoff-
road program (Y page 222) is activated.
At speeds below 30 km/h, the front wheels
loc kc yclically durin gbraking .The digging-in
eff ect ac hieved in the process red ucesthe
stopping distanc eonoff-road terrain. This
limits steering capability. BAS (Brak
eAssist)
i Observ ethe "Importan tsafety notes" sec-
tion (Y page 61).
BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
X Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usua lonce you
releas ethe brake pedal. BA Sisd eactivated. G
WARNING
If BAS has malfunctioned, the braking system
remains available with ful lbrake boosting
effect. However, braking force is not auto-
matically increased in emergency braking sit-
uations and th estopping distance may
increase. BAS PLU
S(Brak eAssist System Plus)
BA SP LUS is only availabl eonvehicles with
DI ST RONIC PLUS.
i Observe the "Important safety notes" sec-
tion (Y page 61).
BAS PLUS assists you in braking during haz-
ardous situations at speeds above 30 km/h
and uses the radar sensor syste mtoevaluate
the traffic situation.
With the hel pofthe radar sensor system ,BAS
PLUS can detect obstacles that are in the path of your vehicl
efor an exte nded period of
time.
At speeds up to approximately 70 km/h ,BAS
PLUS may also detect stationary obstacles,
for example ,stopped or parked vehicles.
Shoul dyou approach an obstacle and BAS
PLU Shas detected arisk of collision, BAS
PLU Scalculates the braking force necessary
to avoid arear-end collision .Should you apply
the brakes forcefully ,BAS PLUS can auto-
matically increase the braking force to alevel
suitabl efor the traffic conditions.
If BA SPLUS demand sparticularly high brak-
ing force, preventative passenger protection
measures (PRE-SAFE ®
)a re activate dsimul-
taneously.
X Keep the brake pedal depressed until the
emergenc ybraking situatio nisover.
ABS prevent sthe wheels from locking.
The brakes will wor knormally again if:
R you release the brake pedal.
R ther eisnol onger any danger of arear-end
collision.
R no obstacl eisdetected in front of your
vehicle.
BAS PLU Sisthen deactivated .Ifyou have
activated DSR (Y page 220), BASPLUS is

WARNING
If EBD ha smalfunctioned, the braking system
remains available with full brake boosting
effect. However, the rear wheels can still lock,
e.g. under full braking. This coul dcaus eyou
to lose control of your vehicle and cause an
accident. You shoul dtherefore adapt your
drivin gstyle to the different handling charac-
teristics.

sion. If PRE-SAFE ®
Brake has detected arisk

R brake the vehicle automatically from a
spee dofuptoa pproximately 20 0km/h
R trigge rpreventative passenger protection
measures (PRE-S AFE®
)( Ypage 45)
Due to the nature of the system, particularly
complicated driving conditions may cause
unnecessar ywarnings or the unnecessary
intervention of PRE-SAFE ®
Brake. To end this,
you can either depress the accelerator pedal
further, activate kickdown or release the
brake pedal.
The braking action of PRE-SAFE ®
Brake is
ended automatically if:
R you drive slowe rthan approximately
15 km /h.
R you manoeuvre to avoid the obstacle.
R there is no longe rany danger of arear-end
collision.
R there is no longer an obstacl edetected in
front of your vehicle.
If you have activated DSR (Y page 220), PRE-

With the help of the rada rsensor system,
PRE- SAFE ®
Brake can detect obstacles that
are in front of your vehicle for an exte nded
period of time.
At speeds up to approximately 70 km /h,

vehicles.
If you approach an obstacle and PRE-
SAFE®
Brake detects arisk of acollision ,the system
will initiall yalert you both visually and acous-
tically. If you do not brake or take evasive
action, the system will warn you by automat-
ically brakin gthe vehicle gently. If ther eisan
increased risk of collision, preventative
passenger protection measures (PRE-SAFE ®
)
are activated (Y page 45). If the risk of colli-
sion remains and you do not brake, take eva-
sive action or accelerate significan tly, the
vehicle may perform automatic emergency
braking. Automatic emergency braking is not
performed until immediately prior to an acci-
dent that can no longe rbea voided. G
